SAFETY GASOLENE-MEASURING TANK- Patented Ju1y17, 1906.

Application filed April 3, 1905. Serial No. 253,495.

To all whom it may concern.-

.Be it known that 1, CHARLES SAUNDERS, a I t citizen of the United States, residing at Saginaw, in the county. of Saginaw and State of Michigan, have invented certain new and useful Improvements in Safety Gasoleneeasuring Tanks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a ,device for measuring gasolene and other volatile explosive liquids. eing aware of the great danger of explosion from gasolene-vapors, the object of my uring tank that it will prevent the escape of gasolene-vapor, except. possiblyin such small amounts as to be practically harmless, and to make the tank as safe as possible against leakage through accident or carelessn ss. Such leakage is, apt to occur. when the common form of tank tom is used.

A further object of my invention is to so construct the tank that it shall be easy and convenient to operate and that it will not be liable to get out of repair during the natural life of the tank.

The means consists in certain devices, their com inations and arrangements, and the equivalents thereof shown in the accompanying drawings, in whichin part, andFig. 2 1s a part vertical section taken on the line as w of Fig. 3. 'Fig. 3 isa partial plan view with the-top of the tank removed.

As is clearly shown in the drawings, the device consists of an outer storage-tank l, having a tight top 2, provided with a screw-cap 3 or similar means for filling the tank. Within the tank 1 is a vertical plunger-pump 4, having its plun'gerrod 4* extending through the top 2 of the tank. A discharge-spout 4 is located just below the top 2 of and within the tank and is arranged to discharge into a measuring vessel 5, mounted inside the tank 1 near its top. The vessel 5 is of unit capacity-say one gallon-and is provided near its bottom with a draw-ofi valve 6, by which the contents 0t vessel 5 can be delivered-outside the tank a gasolene-meashaving a faucet at its bot' igure 1 is a vertical section broker away To impart additional strength to the botom of the vessel 5 and to prevent the vessel from becoming displaced when empty and surrounded by gasolene and also'to form a convenient attachment for the draw ofi. valve 6, I have secured to vessel 5 by soldering or otherwise a tube or trough 5, as shown in Fig. 1, communicating with the vessel 5 by means of a slot, as shown at. 5 in Fig. 3. The draw-off valve 6 is secured to the projecting end of the tube.

For the purpose of indicating when the vessel 5 is filled or nearly filled I provide a floated just beloWIt-he level sel 5, so that when the vessel is full gig, float rises slightly. The float is containe 1n and secured to the under side of the top 2, said tube being open at its lower which closes the tube opening when the valve (5 is opened and a small amount of gasolene is drawn'froni the vessel -5.

To form a tight joint between the opening provide a similar washer 8'. When the pump is not in use, this 'washer 8 rests upon a ,ca 4 on the projecting end of the pump-barre as shown in Fig. 1, ma tight to prevent the escape of vapor.

y the means above described I have produced a gasolene-tank that is at all times sutliciently tight to prevent the escape of vapor, that permits a unit to be withdrawn at a time, and insures that a great quantity cannot be taken out as a ne-' sult of mistake in measuring. This latter re sult is obtained by making the tank 5 of just suflicient capacity to contain a unit charge.
